Configuring cursors on opening

You can configure the following aspects of cursor behavior when you open the cursor:

Isolation level
You can explicitly set the isolation level of operations on a cursor to be different from the current isolation level of the
transaction. To do this, set the isolation_level option. See isolation_level option.

Holding
By default, cursors in embedded SQL close at the end of a transaction. Opening a cursor WITH HOLD allows you to keep
it open until the end of a connection, or until you explicitly close it. ADO.NET, ODBC, JDBC, and Open Client leave cursors
open at the end of transactions by default.
